APPLICATIONSerenity™ disk silencers feature improved insula�on capabili�es and advanced heat reten�on in a space-saving design. This low profile silencer provides extraordinary performance in a compact size, and is excellent in applica�ons where size restric�on is a cri�cal factor.
CONSTRUCTIONIncludes a compressed thermal / acous�cal fiberglasspacked shell. In addi�on to its acous�cal value, the 2" thick packed shell provides a significant reduc�on in the outer surface temperature. Actual values depend on the exhaust temperature and ambient condi�ons. Available bracket op�ons include top mounted, bo�om mounted or none.
FINISH AND OPTIONAL MATERIALS
Flanged inlet and outlet standard. Addi�onal connec�ons, as well as flush mounted inlets, are available. Stainless steel available, consult factory for details.
